Officially telnet is a interactive client service protocol typically
on port 23 and handled by a telnet server.

What protocol underlines things like "POP, IMAP, SMTP, HTTP, LDAP, etc
etc (almost anything that works over TCP rather than UDP)" is exactly
what you said TCP, not telnet. Just because telnet works to interact
with said service doesn't mean it's a telnet service nor that it would
require telnet to work.

You can use netcat just as easily to interact with said services, but
that doesn't make them a netcat service, and often netcat is much
better to interact with the services as it doesn't attempt to
negotiate any terminal settings.
